They are variable rate. About the only way to know for sure is to call and ask Eibach's tech department. Eibach offered two Pro-Line FC kits - they are both discontinued now, so the data may not be readily available. Both of these kits used the same 5513-101 front spring, while the n/a kit used the 5513.102 rear and the turbo kit used the slight stiffer 5520.002 rear spring. Neither one of these kits are meant for the heavier FC convertible - although that never stopped folks from using them.

the Japanese Mazda speed catalog i have lists them thus
Front 3.2/1.4, with 9 coils, 328mm long
rear 3.0/1.7, 13.5coils, 352mm long. the rear has a couple of dead coils, so you can trim it to get the ride height right

179 lbs/in to 78 lbs/in for the front
167 lbs/in to 95 lbs/in for the rear
Attached is a photo of my set of these Eibach n/a springs after they recently came back from being stripped, plated and re-powder coated. I also found the other photo of the n/a rear spring on another thread.
